[PATCH] test-lib: make sure TEST_DIRECTORY has no trailing slash

[Štěpán Němec <stepnem@xxxxxxxx>]

Turns out having `pwd` (which TEST_DIRECTORY defaults to) print $PWD
with a trailing slash isn't very difficult, in my case it went something
like

  ; tmux new-window -c ~/src/git/t/
  [in the new window]
  ; sh ./t0000-basic.sh
  PANIC: Running in a /home/stepnem/src/git/t/ that doesn't end in '/t'?
  ; pwd
  /home/stepnem/src/git/t/

(tmux(1) apparently sets PWD in the environment in addition to calling
chdir(2), which seems enough to make at least some shells preserve the
trailing slash in `pwd` output.)

Strip the trailing slash, if present, to prevent bailing out with the
PANIC message in such cases.
